It was released on 7" vinyl in the United Kingdom on August 26, 2006 and contained the B-side "Oh, Star," and a poster of the band. The song was written by Hayley Williams and Josh Farro. It failed to chart in the United States, however, it was released in Kerrang!s "Class of '06" compilation CD, calling it one of the best rock tracks of that year. There is also a Post-hardcore version of the song, providing a heavier sound and screamed vocals, although it has never been officially released by the band.
